A nurse in a provider's office is talking with a client who takes oxybutynin. The client asks why he does not urinate as often. Which of the following information should the nurse include about the action of oxybutynin?
The medication reduces the rate at which the kidneys filter waste.
The medication decreases the sensitivity of the urethral sphincter.
The medication prevents the bladder muscles from involuntarily contracting.
The medication blocks the nervous system impulse to produce urine.
The Correct Answer is C
A. The medication reduces the rate at which the kidneys filter waste: This is incorrect as oxybutynin does not affect kidney function or the rate at which kidneys filter waste.
B. The medication decreases the sensitivity of the urethral sphincter: This is incorrect because oxybutynin primarily affects bladder muscle contraction, not the sensitivity of the urethral sphincter.
C. The medication prevents the bladder muscles from involuntarily contracting: This is correct as oxybutynin is an anticholinergic medication that reduces involuntary bladder contractions, leading to less frequent urination.
D. The medication blocks the nervous system impulse to produce urine: This is incorrect because oxybutynin works by blocking the action of acetylcholine in the bladder, not by blocking impulses to produce urine.

Correct Answer is D
Explanation
A. A padded tongue blade: A padded tongue blade is not recommended as it can cause injury to both the client and the nurse. It is a common misconception that it should be used during a seizure, but it does not prevent injury.
B. Anticonvulsant medication: While important for managing seizures, anticonvulsant medication is not an equipment item to be placed at the bedside. It is typically administered as per the prescription and monitored by healthcare providers.
C. A nasogastric tube: A nasogastric tube is not relevant for seizure precautions and is used for different medical purposes, such as feeding or gastric decompression.
D. A suction machine: This is correct as a suction machine is essential to clear the airway in case of aspiration during or after a seizure. It helps in maintaining airway patency and preventing complications.
Correct Answer is D
Explanation
A. Take the medication right before eating breakfast: Alendronate should be taken first thing in the morning on an empty stomach, at least 30 minutes before eating or drinking anything. This helps maximize absorption and reduce the risk of esophageal irritation.
B. Chew the tablets thoroughly: Alendronate tablets should not be chewed. They must be swallowed whole to ensure proper delivery and absorption.
C. Drink milk with the medication: Milk can interfere with the absorption of alendronate. It is advised to take the medication with plain water only.
D. Sit upright for 30 to 60 min after taking the medication: This is correct as sitting upright helps prevent esophageal irritation and facilitates the medication's passage into the stomach.
